I don't understand this resistance to turning off track. You are going to have more traffic following your exact track directly aligned below you than crossing you if you turn off to avoid the traffic below you, then a short time later turn parallel to either head back or continue, or divert. You are asking for trouble blundering straight down through everybodies airways tracks, hence the importance of the ICAO requirement to turn off track before commencing descent if able.
So what is the decision? To 'ignore' the ICAO requirement 'because I know better'?
